Abstract
Purpose of Review
In this article, we review why patients may fail medical therapy for benign prostatic hyperplasia (BPH) and by doing so, gain a better understanding of the disease process and how to optimize the care of these patients.
Recent Findings
A growing body of literature has attempted to better characterize the various mechanisms by which patients develop BPH as well as identify predictors of disease progression and treatment failure.
Summary
BPH is a heterogenous disease process. A more personalized approach to treatment, including patient selection for medical or surgical management, would allow us to optimize patient care.
